Is my R9 290 unlocked?

I have an XFX 290 and with flashed Asus 290x BIOS the only thing changed in GPU-Z is the clock speed. 1000Mhz from 947. The Shaders and Texture units are the same.
How can I tell if it's unlocked? I does benchmark better but that might be because the stock clock is almost 50Mhz higher and not because the shaders and texture units are unlocked.

Also, I CANNOT overclock the Memory AT ALL. Which seems a bit strange. Any increase in memory frquency results in lock-ups. Does anyone know why that is?Edited by Leopard2lx - 11/28/13 at 10:02am

Open up GPUZ and see how many Shaders its displaying. If it says 2816 its unlocked.
